libghc-fclabels-doc binary package in Ubuntu Xenial arm64
This package provides first class labels that can act as
bidirectional record fields. The labels can be derived
automatically using Template Haskell which means you don't have
to write any boilerplate yourself. The labels are implemented as
lenses and are fully composable. Labels can be used to /get/,
/set/ and /modify/ parts of a datatype in a consistent way.
.
See "Data.Label" for an introductory explanation.
.
Internally lenses are not tied to Haskell functions directly,
but are implemented as arrows. Arrows allow the lenses to be run
in custom computational contexts. This approach allows us to
make partial lenses that point to fields of multi-constructor
datatypes in an elegant way.
.
See the "Data.Label.Maybe" module for the use of partial labels.

> 1.1.1.0 -> 1.1.2
> - Added partial set/modify versions that act as identity
> when the constructor field is not available.
